I downloaded one of the access_log files from http://www.monitorware.com/. Like any other web access log, we have one line per entry, like this:
64.242.88.10 - - [07/Mar/2004:16:05:49 -0800] "GET /twiki/bin/edit/Main/Double_bounce_sender?topicparent=Main.ConfigurationVariables HTTP/1.1" 401 12846
The first part is the IP address of the caller, followed by timestamp, type of HTTP access, URL referenced, HTTP type, resultant HTTP Response code, and finally, the number of bytes in the response.
We can use Spark to load in and parse out some statistics of the log entries, as in this script:
import pyspark if not 'sc' in globals(): sc = pyspark.SparkContext() textFile = sc.textFile("access_log") print(textFile.count(),"access records") gets = textFile.filter(lambda line: "GET" in line) print(gets.count(),"GETs") posts = textFile.filter(lambda line: "POST" in line) print(posts.count(),"POSTs") other = textFile.subtract(gets).subtract(posts) print(other.count(),"Other")...
